About us

ToornendPartners consists of a team of dedicated and independent specialists with extensive knowledge of sustainability and a strong affinity with the cultural sector. We have more than 50 years of knowledge and experience in the field of construction, buildings and sustainability. We use this knowledge for a wide range of clients who entrust us with their questions.


ToornendPartners was founded in 1971 as an independent consultancy and engineering company that offers high-quality advice to clients, mainly from the cultural sector. Although sustainability in various forms has always been part of the company philosophy, in 2018 we launched a tool to promote sustainability to our clients: the SDG Planner. With this tool, we enable clients to quickly determine the most relevant and effective measures in the field of sustainability and to report on their impact.
